Page 5: Motion I/O Terminal Block
Motion I/O Terminal Block Each axis connected to the UMI-7764 has a motion I/O terminal block to which the following signals are wired: • Amplifier/driver connections • Encoder connections • Limit switch connections • Distributed power connections Figure 2 shows which portions of the terminal block are used for different functionality. -
Page 6: Encoder Terminal Block
Inhibit All signal is asserted, or if the Inhibit Input signal or the controller Inhibit Output signal for that axis is asserted, the Inhibit Output from the UMI-7764 for that axis is asserted. You can configure the axis Inhibit Out signal as active-low or active-high output using switch S1. - Page 7 You must supply a +5 V source to the power input terminal block for proper operation. Refer to Figures 1 and 2 to help you locate the encoder terminals on your UMI-7764 accessory. Figure 4 shows the wiring for a differential encoder.

Page 8: Limit Switch Terminal Block
The encoder inputs are filtered by both analog and digital noise filters. You must use cables with twisted pairs and an overall shield for improved noise immunity. When connecting the encoder to the UMI-7764, you should use at least 24-AWG wire. -

Page 11: Umi-7764 Specifications
Some signals have compatibility defined as signal pass-through. This means the UMI-7764 may have passive filtering on these signals but will not affect the voltage range or current handling capability. Consult your motion controller specifications to determine the allowable voltage range and logic level compatibility of the signal. -

The System Inhibit output signals are used to disable all of the amplifiers. The UMI accessory combines the host bus interlock circuit and the Enable Input signals to create the global System Inhibit signals. The host bus interlock monitors the +5 V pin from the motion controller to verify that the controller is powered and properly connected to the UMI.

The UMI-4A accessory allows for differential inputs for Phase A, Phase B, and Index signals. You can easily accommodate encoders with phase relationships different from Figure 18 by swapping the signals as required by the specific application. The Index pulse must occur when both Phase A and Phase B signals are logic low as shown in Figure 7. -

Encoder Terminal Block For incremental encoder connections, each UMI-Flex4 axis has a separate 8-position terminal block. UMI-Flex4 accepts either single-ended TTL or differential line driver inputs. You can connect open-collector encoders to the UMI-Flex4 accessory by installing a 2.2 k pull-up resistor to +5 V. Note Encoders with line driver outputs are recommended for all applications and must be used if the encoder cable length is greater than 10 feet. - Page 31 24-AWG wire.
